field, in the county of Plymouth and State l of 1,Massachusetts,havejinvented certain new i anduseful- Improvementsin SteeringApparatus for Vessels, and thatfthe following is alf-ull,` clear, and eXact` description of the same`,xreference being had to the accompany-4 ing drawings,`mak1n`g appart thereof,` in

whichi `Figure l, represents a side elevation.` Fig. y 2, representsatop plan.` Fig. 3, represents Y averticalsection taken in the line .fr m, of ,Fg. 2, andFigft,` represents a top view of o the rudderhead andthe hoop on it. l

\ Similar letters wherethey occur in the severalfigures denote like parts. V i `The natureofiny invention consists 1n comdining with uid divided ma, adjustable bars,

supported in the bearing pedestals, which may be forced upagainst `said-nut orfthe e sections thereof,topr`oduce friction between the nut and screw, and to prevent it from o being broken or bentby the sudden action of the sea` against the rudder.` And also in so connecting said bearing pedestals, and the 'parts' connectedwith,` or supportedby them, to the stanchionsby means of guidepins and oblong slots through which said pins pass, thatthe bearing pedestals and all partscon` nected withthem `may move forward and, Nbacfk and up and downin order to follow the ore and aft, `and `up and down move-` 1 ments of the rudderhead. l

` Toenable others skilled scribe thesame with reference to the draw- A, represents therudder` head which may i `be hung in anyfof` the usual Vwell known ways.

` B, is the metallic rin or hoop fitted around the rudder head, as sho-wn in Fig. 4) `and havingprojectionsC, C, thereon, at opposite sides of the rudder head.

" D, D, are twobearing pedestals arranged 31 `,on the stanchions E, E, which are firmly connectedto the deck F. The pedestalsD, a "havein their bases,` at or near each of `their fends oblong slots a, a, through which pins or studs b, Z2, pass into the stanchions E. By this mode of connecting the pedestals to the stanchions,1theyfhave a yielding or adc in the art to make a and use my invention, I will "proceed to de- STEERING APPARATS;

i ment of the rudder when struck by a heavy sea, and the pedestals may rise upv on said o pins-they (the pins) projecting upward far enough for the purpose, so asto yieldup- 4ward when struck in that direction. And

thus theforceof the seais expended on the rudder, by allowing therudder to yield to it,

when by being rigid1 some portion would possibly break or bend enough to prevent 3its complete action. The screw shaftG, having aright andV left'screw cut upon it, is supported in the pedestals D, D, and has upon one of its `ends `a hand wheel H, of the usual construction.`

I, is a divided nut having a female, double, `or right and leftsorew cut in it in which the screw shaftGr, works. The nut I, has upon each of its halves, a horizontal flange c from which riseh up vertically sleeves `or sockets J, J, in which the rounded part fof the bolts K K, are placed and move when the rudder Brion. y

is worked. On the tops of these bolts are cut screws onto which a capped nut is run i"down, to hold it in place. The lower end of the bolt which is flattened or bar shaped passes between the jaws C, C,` formed .on anE extended portion of the rudder head ring, and thusa connection is formed between the screw shaft, and rudder head, rigid lfor all` thepracticalpurposes of steering, and yet free t yieldor move, fore and aft, or up and fdown, tothe springing,or moving of the rudder head under a heavy sea. l `M, M, are two guard rails, lying parallel to, and in cont-act one with each half of the `divided nut. These bars are also supported in the pedestals D, s0 as to move with .all the other moving parts when yielding to the spring of the c rudder. These bars have wedges n; n, at their ends, driven behind them so as to press hard up against the nut I, or its `divided halves. The obj ect of this is to relieve the screw shaft` from the workings of the rudder in a heavy sea, V,and to prevent it from being bent out of its true line,l which would strip its own, or the thread of the nut, or both. Another objectis to wedge up the parts of the nut against the screw shaft, should they become worn, or to produce greater friction between the nut and screw shaft. o

The peculiar advantage of the socket,bolt and open jaws in the vring or band of the rudder head is this, that while one half of f3 12,4ss

the nut is ruiming in one direction, and the other half in a contrary direction, the bolts can freely turn in their sockets, but are always at the saine distance from the center of the screw shaft as the rudder is turned by the running out of the nuts, and when hard up, the jaws C, slip on the bolts, and thus increase, the leverage between the jaws and bolt, and in this position the rudder will move a shorter distance by a given number of turns of the hand wheel than when' the nuts are midway of the shaft but the leverage is greater, and the rudder more easily managed. This was not the case in a former invention of mine, for there the leverage diminished as the nuts run out on the screw shaft, and it required more turns of the shaft to move the rudder when thus run out, than when they were yin the center of the screw shaft.

Having thus fully describedthe nature of l my invention what I claim therein as new and desire to secure by Letters Patent is 1. In combining with the divided nut the adjustable guide and guard rails, substantially in the manner and for the purpose set forth.

2. I also claim the supporting of the pedestals upon the stanchions by means of long pins or studs passing through oblong slots in the pedestals, and into said stanchions, for the purpose of allowing the pedestals and several parts connected therewith to move fore or aft-up or down, to accommodate themselves to any rising or falling, or springing or bending of the rudder post, substantially as described.
